It was investigated whether normal ecocement manufactured using as raw materials large amounts of urban wastes such as incinerator ash and sewage sludge, could he used for reinforced concrete. It was confirmed that the fresh properties, strength properties, durability, steel corrosion protecting performance, leaching of heavy metals and workability of the concrete using normal ecocement that contains a reduced amount of chloride ions of around 0.05% were equal to those of concrete using normal portland cement. The results of test executions in several field also confirmed that concrete using ecocement demonstrated Workability equal to that of general concrete. Based on these results, it was concluded that normal ecocement can he used for reinforced concrete.
